I know the PS audio in United States, has been messing around with switching power supplies, Not in production at this time. I do like their results with using a vacuum tube/valve for the input stage in there amplifiers. in my experience of diy World certainly with preamps using a massive power supply has had a great sonic benefit. I’m thinking that with a really well designed switching power supply with 10 times the current needed might be interesting.
Very interesting using a AD, FPGA and DA converter to set the sliding bias at it's optimum value!

So why are Jeff Rowland amps the best solid state amps in the world???
